CiteScore: 3.08ℹ
CiteScore is the number of citations received in one year (Y), to documents published in the three previous years (Y-1, Y-2, Y-3), divided by the number of documents published in those same three years (Y-1, Y-2, Y-3).

Source Normalized Impact per Paper (SNIP): 1.221ℹSource Normalized Impact per Paper (SNIP):2015: 1.221SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.

We chose the orb spider Zygiella x-notata as an invertebrate organism to investigate alterations in web geometry caused by ageing.
